PNG to PDF Converter
Turn a PNG into a PDF document without losing a pixel. This is the right conversion for screenshots, diagrams and scanned pages that need to be submitted as documents — PNG keeps text and lines crisp, and the PDF carries them across exactly.

Format comparison
PNG vs PDF
PNG (Portable Network Graphics)
LosslessStores every pixel exactly as it was saved, so nothing is lost however often the file is opened and saved.
- Pixel-perfect: ideal for screenshots, logos and text
- Supported everywhere, including every browser
- Photographs make large files — often several times the JPG size
PDF (Portable Document Format)
DocumentA fixed-layout document format that looks the same on every device and printer.
- Opens identically everywhere, and prints reliably
- Holds many images as pages of one file
- A document rather than an image, so it is awkward to edit or embed
PDF stores a PNG the way PNG stores itself: compressed losslessly, with every pixel preserved. Nothing is decoded and re-encoded, so the image inside the document is exactly the image you started with.
That makes this a particularly good pairing for the kind of content PNGs usually hold. Text, diagrams, screenshots and line art all depend on sharp edges, and both formats keep them perfectly — where routing the same content through JPEG would smear precisely the boundaries that make it readable.
Transparency becomes white
This is the one surprise, and it is worth knowing before rather than after.
A PDF page is a sheet of paper. Where your PNG was transparent, the paper shows through — and paper is white. So a logo with a transparent background becomes a logo on a white rectangle, and if the document is later placed on a coloured background, that rectangle is visible.
For most uses this is exactly right: a screenshot or a scanned page is meant to sit on white. It only causes trouble when you were relying on transparency to blend into something else, and in that case a PDF is probably the wrong container.
Semi-transparent areas are preserved as a soft mask, so a drop shadow fades into the white rather than developing a hard edge.
Size
The PDF is usually within a few percent of the PNG, since the compressed data is carried across as it is. Occasionally it comes out noticeably smaller, when the PNG was saved with weak compression and the PDF writer re-compresses the same pixels more efficiently — still losslessly, just packed better.
Quality
Quality and file size
There is no quality setting, because nothing is discarded at any point.
What still governs how the document prints is the pixel count of your PNG. A screenshot captured at 800 pixels wide is 800 pixels wide inside the PDF, and printing it across a page will look soft — not because of the conversion, but because that is how much detail exists.
For anything intended for print, capture or scan at a size that suits: roughly 300 pixels per printed inch. An A4 page wants about 2480 × 3508.
When JPG would be the better source
If your PNG is a photograph, converting it to PDF produces a much larger document than it needs to be — PNG is inefficient for photographic content, and the PDF inherits that. Convert the photo to JPG first and then to PDF: the file will be a fraction of the size, and at a high JPEG quality the difference is invisible.
Keep the PNG route for screenshots, diagrams, charts, line art and text — content where lossless genuinely matters.
What this is good for
- Screenshots submitted as documents. Support tickets, expense claims and evidence attachments frequently want PDFs.
- Diagrams and charts going into reports or submissions.
- Scanned pages saved as PNG that need to become documents.
- Design proofs sent for approval, where a PDF is the expected format.
- Anywhere a form accepts PDF only, which is a large share of the reason anyone does this.
Several images into one document
This tool makes one PDF per image. To build a multi-page document, convert each image and then merge the PDFs — most operating systems now include a tool for that, as does any PDF reader with editing features.
Because nothing is re-encoded at any stage, the images survive the whole process untouched.
Text in the image stays an image
Worth being explicit, because it disappoints people otherwise: converting a screenshot of text to PDF does not make the text selectable or searchable. The PDF contains a picture of text, not text.
Turning a picture of words into real words requires optical character recognition, which is a different kind of tool entirely. If you need a searchable document, you need OCR — not a format conversion.
Going the other way
PDF to PNG renders pages back to images, and it is the right choice for documents for the same reason this page is: lossless, so text stays crisp.
What happens to your file
PDF creation runs on our server, since browsers cannot write PDF documents. Your upload is deleted as soon as the conversion finishes, the result is deleted as you download it, and anything never collected is swept automatically.
Privacy
What happens to your file
This tool runs on our server, so it works the same on every phone and computer. Your file is uploaded, and this is exactly what happens to it:
- Stored outside the public web root under a random name, never under your file's name.
- Processed, with the original upload deleted immediately — whether it succeeded or failed.
- The result sits behind a signed link that only you receive, which stops working after 20 minutes, and the file is deleted the moment you download it.
- Anything never collected is deleted automatically within 30 minutes.
- The image itself is never logged or kept. If a conversion fails, we record the formats involved and the error — not the file.
- Camera metadata, including any GPS coordinates recording where a photo was taken, is removed from the result. Only the rotation needed to show the image the right way up is kept.
Questions & answers
PNG to PDF: frequently asked questions
Will my transparent background be kept?
Not as transparency. A PDF page is a sheet of paper, so transparent areas show white. For a screenshot or scanned page that is exactly right; it only matters if you were relying on transparency to blend into something else, in which case a PDF is probably the wrong container. Semi-transparent areas such as soft shadows do fade properly rather than developing a hard edge.
Does converting lose any quality?
None. The PNG is stored losslessly inside the PDF, so every pixel is preserved exactly. Nothing is decoded and re-encoded at any point.
Will the text in my screenshot be searchable?
No. The PDF contains a picture of text, not text. Making it searchable requires optical character recognition, which is a different kind of tool — a format conversion cannot do it.
My PNG is a photograph. Is this the right route?
Probably not. PNG is inefficient for photographic content and the PDF inherits that, so the document comes out far larger than it needs to be. Convert the photo to JPG first and then to PDF — at a high JPEG quality the difference is invisible and the file is a fraction of the size.
Why is my PDF smaller than the PNG?
Because the PNG was probably saved with weak compression, and the PDF writer packs the same pixels more efficiently. It is still lossless — the image is identical, just stored better.
Can I combine several PNGs into one PDF?
Not with this tool, which makes one PDF per image. Convert each and merge the PDFs afterwards — most operating systems include a tool for that. Nothing is re-encoded at any stage, so the images stay untouched.
